Proportional Cake-Cutting
A proportional cake-cutting is a kind of fair cake-cutting. It is a division of a heterogeneous resource ("cake") that satisfies the proportionality criterion, namely, that every partner feels that his allocated share is worth at least 1/n of the total. Two assumptions are usually made when proportionality is discussed: The valuations of the partners are non-atomic, i.e., there are no indivisible elements with positive value. The valuations of the partners are additive, i.e., when a piece is divided, the value of the piece is equal to the sum of its parts.

The EU's Green Deal
In December 2019, the European Union introduced its Green Deal in which the ecological crisis is prioritized. In doing so, the EU seems to be breaking with its traditional green growth discourse. Does it? In this article, we seek to find out whether and to what extent the EC indeed has such a revolutionary cultural, economic and political agenda in mind with its Green Deal. While the green growth discourse presumes a growth-based economy that must become greener, the degrowth discourse questions the growth model and perceives it as ecologically irresponsible. If the European Green Deal represents a third alternative, then it will somehow succeed in prioritizing ecology without welfare loss. To ascertain to what extent the European Green Deal is that third alternative, three preliminary steps need to be undertaken. The first step consists in a brief exposition of the key features of the traditional green growth discourse, as propounded by the EC and its various allies. Thereafter, the overlaps between the green growth discourse and the European Green Deal are noted. In the third section, the latter’s divergences from that previous model are highlighted. In the final section, the main question of the article is answered. It is also suggested that specific interpretations and implementations of the European Green Deal could possibly turn the original communication into an alternative to both green growth and degrowth.

Loathly Lady
The loathly lady (Motif D732 in Stith Thompson's motif index), is a tale type commonly used in medieval literature, most famously in Geoffrey Chaucer's The Wife of Bath's Tale. The motif is that of a woman who appears unattractive (ugly, loathly) but undergoes a transformation upon being approached by a man in spite of her unattractiveness, becoming extremely desirable. It is then revealed that her ugliness was the result of a curse which was broken by the hero's action.

Uncontrolled Outdoor Access for Cats
Outdoor access for companion cats is a controversial topic. Some have suggested that outdoor access can negatively impact the welfare of companion cats through increased risks of disease and parasites, injury or death due to traffic, predation or ingestion of toxins, and becoming lost. In addition, cats can negatively influence their environments due to the predation of small birds and mammals, and they are sometimes a nuisance to human neighbors. Despite these concerns, recent estimates suggest that many owners still allow their cats outside, likely because it also provides cats with exercise, and allows them to perform natural behaviors, such as hunting, exploring, and climbing. While some suggest that cats need outdoor access, others recommend ways for cats to meet these needs indoors by providing enrichment and properly supervising cats during outdoor access.

Fair Pie-Cutting
The fair pie-cutting problem is a variation of the fair cake-cutting problem, in which the resource to be divided is circular. As an example, consider a birthday cake shaped as a disk. The cake should be divided among several children such that no child envies another child (as in a standard cake-cutting problem), with the additional constraint that the cuts must be radial, so that each child receives a circular sector. A possible application of the pie model might be for dividing an island’s shoreline into connected lots. Another possible application is in division of periodic time, such as dividing a daily cycle into "on-call" periods.

Changing the PrEP Narrative
Pre-exposure prophylaxis, when taken appropriately, is an effective and well-tolerated option to assist in prevention of HIV transmission. This medication has been tested in several patient populations and has shown efficacy across the board. Further research is needed to advance the study and implementation of PrEP in cis-gender women in order to stop the spread of HIV in this vulnerable group.

Electric-Powered Wheelchairs Driving
Electric power wheelchairs (EPWs) enhance the mobility capability of the elderly and the disabled, while the human-machine interaction (HMI) determines how well the human intention will be precisely delivered and how human-machine system cooperation will be efficiently conducted. A bibliometric quantitative analysis of 1154 publications related to this research field, published between 1998 and 2020, was conducted. We identified the development status, contributors, hot topics, and potential future research directions of this field.

Step-by-Step Model for Implementing Open Innovation
Open innovation has attracted wide interest since it first appeared in the 2003 book by Chesbrough. It proposed that companies combining internal and external ideas when innovating would benefit more than by adhering to the traditional research and development model. As many definitions have been proposed for this term since then, it appears that open innovation is not something stationary and is constantly evolving. At this time, the most prevalent definition seems to be that open innovation is the use of purposive inflows and outflows of knowledge to accelerate internal innovation, and expand the markets for external use of innovation, respectively. This means that firms wanting to advance their technology can and should use both internal and external ideas. Even though there are several definitions for open innovation, their common thread is the creation of relations and collaborations in order to create something new with the resources at hand. The differences in the definitions usually refer to different scopes concerning resources, the degree of openness, etc.

Cognitive Chronometry
Mental chronometry is the study of reaction time (RT; also referred to as "response time") in perceptual-motor tasks to infer the content, duration, and temporal sequencing of mental operations. Mental chronometry is one of the core methodological paradigms of human experimental and cognitive psychology, but is also commonly analyzed in psychophysiology, cognitive neuroscience, and behavioral neuroscience to help elucidate the biological mechanisms underlying perception, attention, and decision-making across species. Mental chronometry uses measurements of elapsed time between sensory stimulus onsets and subsequent behavioral responses. It is considered an index of processing speed and efficiency indicating how fast an individual can execute task-relevant mental operations. Behavioral responses are typically button presses, but eye movements, vocal responses, and other observable behaviors can be used. RT is constrained by the speed of signal transmission in white matter as well as the processing efficiency of neocortical gray matter. Conclusions about information processing drawn from RT are often made with consideration of task experimental design, limitations in measurement technology, and mathematical modeling.

Bonded Warehouse
A bonded warehouse, or bond, is a building or other secured area in which dutiable goods may be stored, manipulated, or undergo manufacturing operations without payment of duty. It may be managed by the state or by private enterprise. In the latter case a customs bond must be posted with the government. This system exists in all developed countries of the world. Upon entry of goods into the warehouse, the importer and warehouse proprietor incur liability under a bond. This liability is generally cancelled when the goods are: While the goods are in the bonded warehouse, they may, under supervision by the customs authority, be manipulated by cleaning, sorting, repacking, or otherwise changing their condition by processes that do not amount to manufacturing. After manipulation, and within the warehousing period, the goods may be exported without the payment of duty, or they may be withdrawn for consumption upon payment of duty at the rate applicable to the goods in their manipulated condition at the time of withdrawal. In the United States, goods may remain in the bonded warehouse up to five years from the date of importation. Bonded warehouses provide specialized storage services such as deep freeze or bulk liquid storage, commodity processing, and coordination with transportation, and are an integral part of the global supply chain.
